For the answer to the question above, <span>Griffith heated a culture of a disease- causing the strain of the bacteria, which killed the bacteria but didn't destroy the DNA. When he mixed the heat-killed, disease-causing bacteria with live harmless bacteria, the DNA from the disease-causing bacteria was infused to the live bacteria. This kind of bacteria and their offspring caused pneumonia to the mice.</span>
Answer: Alveoli
Explanation: Alveoli is the air sacs in the lungs through which oxygen and carbon dioxide diffuse into and out of the blood.
Answer:
Disequilibrium
Explanation:
Homeostasis is a relatively stable equilibrium
While Disequilibrium is unsteady or unstable
Answer:
D. The native snail species will compete for resources with the invasive species and destabilize the ecosystem
Explanation:
In Ecology, an invasive species refers to a species of organism that is foreign i.e. non-native to a particular habitat or environment. They are characterized by the ability to proliferate in growth and compete for space and nutrients with the native species in the habitat they are introduced to.
In this case, the giant african land snail, which is an invasive species, if introduced into a stable ecosystem will compete for resources with the native species of that ecosystem leading to the destabilization of the ecosystem.
Answer:
At least 17 PCR cycles or 16 PCR cycles
Explanation:
As we know -
In one chain of heating and cooling of polymerase chain reaction (PCR), the strands of DNA gets doubled.
The general mathematical representation of this is
where "n" is the number of PCR cycles.
It is given that DNA strands to be produced is 16 times the original quantity of DNA.
So the PCR cycle must be carried out at least 17 times in order to have DNA strand not less than 16 times the original quantity of DNA
